‘夏黑’葡萄密植园间伐及丰产栽培技术

Intermegiate cutting and high yield techniques of‘Summer Black’dense planting vineyard

‘夏黑’葡萄是一个早熟无核品种,已在全国大面积发展。但因其长势旺盛,易造成通风透光不良,导致葡萄品质及产量下降。近年来,大树冠栽培模式在减少种植密度基础上可保持葡萄有相当产量,改变传统葡萄园用工多的不足,受到广大果农的青睐。对‘夏黑’葡萄园进行间伐处理,并运用“一”字形树冠进行老园改造,加上适宜的新梢管理、肥料施用、花果梳理及病虫防治等,获得良好的效果。这种省工省时又省肥的新型栽植模式,操作简单,可有效弥补传统栽培方式劳动力密集的缺陷,将成为葡萄生产的主要发展方向。

’Summer Black’ is a early-maturing seedless grape variety,and has been widely developed throughout the country.However,due to its vigorous growth,the vineyards were prone to be of worse ventilation and light transmission,resulting in a decline in grape quality and yield.In recent years,the large canopy cultivation model had been favored by fruit farmers,it could maintain stable yield at some lower planting density,which had changed the more work of traditional vineyard.The intercutting treatment of the vineyards of ’Summer Black’ was carried out,and the low density planting was used with a "一" shape,and the suitable new shoot management,fertilizer application,flower and fruit management were obtained.This new planting mode,which saved time and fertilizer,was simple in operation and effectively maked up for the labor intensive defects of traditional cultivation methods,and would become the main development direction of grape production.
